Specification forming part ot'` Letters Patent To allwhom it mrzytconcern:

Beit known that I, J; D. WILLOUGHBY, of Washington city, District of Columbia, have invented a new and improved `mode of steering a boat without any person being on board to steer it.'

The 'object aimed at is to send a small boat an enemys. vessels, orv to drag a grapplingiron through the water to remove torpedoes, and I do hereby declare that the following is a full and exact description thereof, reference being-had totheaccompanying drawings, and

The nature of my invention consists in steering. a boat by two 4lines or cords, or theirequivalents. `zllhese cords being each vsome miles long arewound on tworeels that workindependently of each other. The reels are cord is attached toeach endl of the cross-tiller ontheboat, as in Figures 3 and 4.; oreach end of thecord may pass around a pulley and be fastenedrdirectly to the rudder, as seen in Fig.2.V .v f

Fig.- 1 is a plan'view of the boat. Figs. 2 and 4Bare topviews of a portion ofthe stern.`

Tension is produced on the cords, when desired, by bringing friction-breaks to bfear uponthe periphery of -the reels.V If it is defriction-brake must be pressed on the righe hand reelwhich will draw the rudder B into the position it now stands in, as-seen in Fig. 1. While thetension on therightfhand cord is continued the pulling of' the cord on the rightf hand side of fthe cross-bar and' also the'position of the rudder bothV incline the front end of the boat to the right.

Figs. 2 and 3 are modifications of thesteer- I November z5', i864.

e BOATS FROM ANOTHER BOAT.

No. as. ier'aqtea'nme 6, isst emulated ing device, as shown in Fig. 1f In Fig. 2 the Cord f f passes from the end of the tiller c around pulleys e e, and backto the reels, which reels are-not shown, as they are no part of this invention'. By producing tension v on i these cords the same results are obtained as in Fig. 1. Fig. 3 shows' shortl cords ff extending from the tiller c to the levers I I.' The cords o o'run from the outer end of- I I to the reels, and arel operated the same' as the other figures. Other modifications might be shown; but enough has been' presented to show how the ,tension of the cords and the 'position of the rudder can be made to mutually' assist in steering the boat.'

It is'evident that if the cords were attached to each side of the boat,- and in no way connected .Withjthe-frudder, that tension on` the rightfhand'cor'd would incline the boat to the righujust.incproportion-to the tension ap- Vpliedapd the distance thecord was attached from the'centerl of fthe boat longitudinally.

It isalso obviousthat if the cords were attached to the cross-tillers c, and rin no other way connected with theboat,A thattension on the'righthand cord would. throw the rudder to the leftrin which case the rudder would Vincline the-boat to the left, but the tension of the cord which holds the rudder being on the right-hand side of the boat wouldvineline the boat to the right, in which case each force would operate against the other; butby attaching the cords to the cross-tiller c or rudder B, and then agound some point on the boat, as shown, th"e ltension of the cords and position of the rudder both vact i'n the same direction and 'make it aneasy matter to steel a boat bythe use of two cords, described and represented.

Having thus full-y described my invention,

V`what I claim,v and desire to. secureby Letter.

Patent, is-

Attaching the steeringfcordsff to the cross tiller c or rudder B,and passing themarouni solne point/on the boat, so as to cause the ten .sion of either cord .to pull the rudder into: position that willfincline or steer the boat i the same directionthat it is inclined by th tension of the cord, substantially as describe and represented.
